Method and apparatus for LED display optical blending

Abstract

A method for assembling an LED display includes the steps of: preparing a prefabricated diffuser film containing a light diffusion agent; mounting a plurality of light emitting elements on a substrate, thereby forming a plurality of gaps among the plurality of light emitting elements; filling the plurality of gaps with a black resin to form a planar surface composed of top surfaces of the plurality of light emitting elements and top surfaces of the black resin in the plurality of gaps; applying a transparent resin layer over the planar surface; and affixing the prefabricated diffuser film on the transparent resin layer. The resulting LED display has a plurality of light emitting elements surrounded by a black resin to form a checkered surface, a transparent resin layer affixed to the checkered surface; and a diffuser film affixed to the transparent resin layer by an adhesive.
